"G-d's glory will be revealed, and all flesh will see together, for the mouth of G-d has spoken"
(Isaiah 40:5)

Nowadays, we can only believe in G-d, for we cannot see Him. In the days of Moshiach, however, G-d's light will be revealed so clearly that all flesh will see it.(Days of Moshiach)
(L'Chaim)

Regarding what is written in Song of Songs (4:8), "Sing from the beginning with faith," in the Messianic Era, we will sing from the beginning -- even before the miracle -- merely on the promise of the Prophet. We will not wait until his word comes true, so strong will be our faith(Shnei Luchot Ha'Brit)
(L'Chaim)

As both a genius and tzadik, the Moshiach will see through the sham and hypocrisy of this world.

Thus, the prophet foretold (Isa. 11:3), "He will sense the fear of the L-rd, and he shall not judge after the sight of his eyes, nor decide after the hearing of his ears."(The Real Messiah, by Aryeh Kaplan)
(L'Chaim)

"For a small moment have I forsaken you, but with great compassion shall I gather you in." (Isaiah 54:7)

When Moshiach comes and G-d's great compassion will become manifest, everyone will see how this entire lengthy exile was in fact "a small moment".
(Chasidic discourse of the Previous Rebbe)
(L'Chaim)

"All flesh shall come to bow down before Me"
(Isaiah 66:23)

At the time of that supreme revelation of the Divine Presence, all of humanity -- even persons so unspiritual as to be described as "flesh" -- will attain a level of perceptiveness that will inspire them to bow down humbly before their Maker.
(Likutei Torah of Rabbi Shneur Zalman)
(L'Chaim)

The chains of exile are stronger than mere physical chains.

They capture the mind.

Freedom becomes too high a concept to grasp.

Learning about Moshiach frees us from these chains and lifts our minds above the Exile.
(Rebbetzin Yehudis Heller, obm)
(L'Chaim)

"...Certainly the Creator is the Supreme Ruler -- provided we can push off His actual reign to some later date.

It would be too inconvenient having the Messiah come today!

We do not wish too drastic changes in our lives.

We have certain `business deals ' to work out yet, certain vacation trips to go on. We are not ready for greater piety just yet.

`The L-rd will reign' -- but not now.

Such are the reservations and hesitations that hold back the redemption of Jewry and of mankind.

The Divine kingship must be accepted in the present.

Only thus can we fit harmoniously, in honor, in the cosmos that He created for His glory.(Rabbi Irving M. Bunim, obm)
(L'Chaim)

"And I shall turn their mourning into joy," (Jeremiah 31:8). It is obvious that when the Temple is rebuilt, there will be no more mourning on Tisha B'Av. But why should it become joyful? On Tisha B'Av the Temple was destroyed because of Israel's sins which aroused Divine anger. Nevertheless, though the visible aspect of this anger was outright punishment, its ultimate motivation was G-d's intense love of His people. It was precisely this love that caused Him such distress when His children sinned. If there were no such love, their conduct would be of no consequence to Him.(Rabbi Shneur Zalman of Liadi)
(L'Chaim)

When Moshiach comes, what will be the role of all the revived spiritual leaders of the preceding ages who, beginning with Moses, had successively headed their respective generations as the leader?

Moshiach will not cause them to slip from their respective spiritual rungs; on the contrary, his coming will upgrade the spiritual status of all things and all people, including these leaders.

Thus, Moses will come to the Land of Israel at the head of the generation of the wilderness.
(The Rebbe, 1985)
(L'Chaim)

Even the great minds must lay aside their intellects and not be ruled by their reason and knowledge, for they are susceptible to being misguided by their intellect to the point that their end may be a bitter one.

The essential thing in these times of the "footsteps of Moshiach" is not to follow intellect and reason, but to fulfill Torah and mitzvot wholeheartedly, with simple faith in the G-d of Israel.(Rabbi Sholom Ber of Lubavitch)
(L'Chaim)

Suddenly he will come

Rabbi Menachem Zev Greenglass of Montreal related that in the early '50s, he and a few other chasidim were standing outside the Rebbe's room discussing the coming of Moshiach and how it would happen.

In the midst of their discussion the Rebbe's door opened suddenly -- without their being prepared -- and the Rebbe'stepped out, explaining: "This is how he will come."

The Brisker Rav, Rabbi Yitzchak Zev of Brisk, wrote:

"It is not enough to believe in the concept of Moshiach but we must look forward to his coming every day, as Maimonides writes that whoever does not look forward to his coming is a heretic.

"It is not enough to believe that he will come but as we say in our prayers, 'We hope for Your salvation all day,'-- we must yearn for Moshiach's coming every moment of every single day."(Hagadah Beit HaLevi)
(L'CHAIM)

In their own days our Sages said that the study of Torah is equivalent to the performance of loving-kindness. For with them the principal service was the study of Torah and therefore they were great scholars.

However, with the advent of Moshiach, there is no way to truly cleave unto G-d and to convert darkness into light, except through a corresponding category of action, namely the act of charity.(Igeret HaKodesh 9, Rabbi Shneur Zalman of Liadi)
(L'CHAIM)

"On Rosh Hashana, my soul ascended to the palace of Moshiach, and I asked Moshiach, 'Master, when are you coming?' And he answered me, 'By this you will know: when your teachings are publicized and revealed in the world and your wellsprings are spread forth...'"(The Baal Shem Tov)(L'CHAIM)

Proclaim to all our love; walk in the midst of our camps; seek the redemption from our exile; reveal the end of exile when You will acquire us again; come swiftly to have mercy upon us; proclaim that we are Your chosen people and we will acknowledge You as our G-d.(From the Yom Kippur prayers)
(L'Chaim)

When the Ark is opened before the Torah reading on the festivals, we pray: "May there be realized in us the verse [describing Moshiach] which states, 'The spirit of G-d shall rest upon him, the spirit of wisdom and understanding, counsel and strength, knowledge and the fear of G-d.'"

Since within every Jew there is a spark of Moshiach, every Jew can ask that this verse be fulfilled with respect to the spark of Moshiach within his soul.

Thus, this prayer is appropriate for every Jew, regardless of his spiritual standing.(The Rebbe, 5743)
(L'CHAIM)

The light which the Jewish people yearn for is the light of Moshiach, as it says in Genesis, "G-d saw the light that it was good."

This teaches us that G-d yearned for Moshiach and Moshiach's deeds even before He created the world and hid this light for Moshiach and his generation under his Divine throne.(Pesikta Rabbatei, ch. 36)
(L'Chaim)

When a person experiences a redemption in a personal sense, i.e., his Jewish core is revealed with happiness and joy, he will increase his Jewish practice.

This, in turn, will "bring salvation and deliverance to the entire world," as the Rambam'writes, and will bring about the Redemption.(The Rebbe)
(L'Chaim)

Rabbi Yitzchak Meir Alter of Ger, said: "Before the exodus from Egypt, the Torah states, 'The Children of Israel groaned.' Prior to this, the Children of Israel were sunk in a spiritual exile so great that they did not realize the severity of their exile. It was only after they felt the exile that G-d redeemed them. This is also the case with the end of days. The Jewish people will forget that they are in exile, which will, G-d forbid, strengthen the exile. When we recognize that we are in exile , and this realization causes us to groan, the redemption will come."
(L'Chaim)

The main goal in creating Adam was to bring forth King David and his descendants, the most important one being Moshiach.

This is hinted to in the acrostic for the Hebrew word "Adam": "alef" stands for Adam, "dalet" for David and "mem" for Moshiach. The principal purpose of creation was for the generation of Moshiach.(Midbar Kodesh, the Belzer Rebbe)
(L'Chaim)
